Description

The present invention relates to a cleaning agent composition, and mainly relates to a cleaning agent composition suitable for cleaning / removing stains adhering to a hard surface such as metal, plastics, glass, and ceramics. In particular, the present invention relates to a detergent composition suitable for cleaning and removing stains adhering to manufacturing equipment in a food factory, a beverage factory, etc. by CIP cleaning.

In recent years, in beverage factories, food factories, etc., it has become difficult to disassemble and clean the manufacturing equipment due to the increase in the size of the manufacturing equipment and the increase in the cleaning frequency due to the increase in the number of manufactured varieties. Therefore, instead of disassembling and cleaning, CIP cleaning (CIP cleaning) that cleans and removes residual dirt by filling the manufacturing equipment such as piping, sterilizer, and filling machine with the cleaning liquid and circulating it, or by spraying the cleaning liquid into the manufacturing equipment. The cleaning in place method is widely adopted.

For this CIP cleaning, one or more cleaning agents selected from an alkaline cleaning agent, an acid cleaning agent, a bactericidal agent, and the like are used. For example, in general, CIP cleaning is 1. Wash with water, 2. Alkaline cleaning, 3. Rinse with water 4. Acid cleaning, 5. Rinse with water, 6. Sterilization, 7. It is done in a process called water rinsing. However, there are cases where a part of the above steps is omitted, the order of the above steps is changed, or the same steps are repeatedly carried out, depending on the compounding components of each cleaning agent or the type and state of stains.
When the target stain is mainly a food residue, the food residue includes organic stains such as proteins, fats and oils and carbohydrates, and inorganic stains such as calcium carbonate, calcium phosphate and calcium silicate. Some of the above-mentioned organic stains are heat-denatured and strong, which can be seen in sterilizers and the like.

Among the above-mentioned cleaning agents, the alkaline cleaning agent has conventionally been remarkably remarkably soluble in alkalis such as sodium hydroxide, which are excellent in decomposition / removal property and economy of organic stains, and hardness components and inorganic stains contained in the water used. A detergent containing an excellent metal ion sequestering agent such as ethylenediamine tetraacetate and, if necessary, a polycarboxylate, a phosphonate, a low-foaming surfactant, or the like is used.
When cleaning by the CIP method or the like using such an alkaline cleaning agent in a manufacturing facility or the like, generally, the highly concentrated cleaning agent is stored in a large-capacity tank or the like, and the highly concentrated cleaning agent is used. Usually, it is diluted and used so that the alkali concentration becomes 0.5 to 5% by mass.

Highly concentrated alkaline cleaning agents include strong alkaline agents 25-40% by mass, HLB3-18 nonionic surfactants 0.1-7% by mass, aminocarboxylic acid-type chelating agents and oxycarboxylic acid-type chelating agents. 0.2 to 10% by mass of one or more chelating agents selected from, 0.5 to 15% by mass of one or more compounds selected from 2-methylbutyric acid, 3-methylbutyric acid and their alkali metal salts or lower amine salts. A high-concentration strong alkaline water-soluble composition (Patent Document 1), a metal sequestering agent containing ethylenediamine tetraacetic acid or a salt thereof in an alkaline agent such as sodium hydroxide, a maleic acid homopolymer having an average molecular weight of 1000 to 3000, or these. A cleaning agent composition for a washing machine (Patent Document 2) and the like, which comprises at least one selected from the water-soluble salts of the polymers of the above, are known.

Highly concentrated alkaline detergents are desirable because of costs such as manufacturing, container and transportation costs, as well as reduction of carbon dioxide emissions associated with transportation costs, etc., but detergents containing high concentrations of alkali and chelating agents are desirable. Storage stability deteriorates, especially with highly concentrated detergents containing ethylenediaminetetraacetic acid and its salts together with 26% by mass or more of sodium hydroxide, crystal precipitation and freezing occur during long-term storage, resulting in poor storage stability. The problem arises. When such a highly concentrated detergent is stored in a storage tank, as the liquid level drops with the use of the detergent, the water content of the detergent adhering to the upper wall surface of the tank evaporates and solidifies on the wall surface. When the next detergent is replenished and the detergent solution comes into contact with the solid, ethylenediamine tetraacetate, which is inferior in solubility, precipitates, which becomes nuclei and promotes crystal precipitation and freezing. However, it may clog the detergent supply port and the detergent supply pump, and eventually cause the detergent supply pump to malfunction. As described above, the cleaning agent compositions described in Patent Documents 1 and 2 have poor storage stability when stored for a long period of time, and crystals are precipitated when stored in a detergent receiving tank for a long period of time. There was a problem that it would freeze or freeze.
